Planetarian is a single-player indie action-adventure game that puts you in charge of the World Tree, a mystical entity that rules over multiple planets. The game combines third-person shooter mechanics with bullet hell elements, forcing players to navigate intense combat scenarios while dodging a relentless barrage of projectiles. Your journey takes you across seven different planets, each with unique environments ranging from harsh deserts to lush forests, each with unique enemies ranging from otherworldly creatures to sci-fi foes.
